Name

       susa2 - Find USNO-SA2.0 Catalog stars in a square on the sky

Synopsis

       susac [options] [-b or -j] ra dec

Description

       suac  finds  all of the U.S. Naval Observatory SA2.0 Catalog objects in a specified region of the sky and
       lists their sky positions and magnitudes in order of brightness. Output is to standard out, unless the -w
       flag is set, in which case it goes to objectname.uac or search.uac. It is a link to scat.

Options

       -a  list single closest catalog source -b <RA> <Dec> Output B1950 (FK4) coordinates around this center -d
       Sort by distance from center instead of flux -h Print heading, else do not -j  <RA>  <Dec>  Output  J2000
       (FK5)  coordinates  around  this  center  -m  [<bright  magnitude>]  <faint  magnitude>  Limiting catalog
       magnitude(s) (default none, bright -2 if only faint is given) -n <num> Number of brightest stars to print
       -o  <name>  Object name used to name output file -r <radius> Search radius in arcsec (default 10) -s Sort
       by right ascension instead of flux -t Tab table to standard output as well as file -u <num> Plate  number
       for  catalog  sources  (0=all)  -v  Verbose listing of processing intermediate results -w Write tab table
       output file imagename.uac
